Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 45mm, the TalkBand B1 is the safer pick — it stays proportionate down to roughly 20mm, where the TalkBand B3 starts to hang over the edge. Above 45mm both sit cleanly, and the TalkBand B3 gives you more presence.
The TalkBand B3 wears larger than the TalkBand B1 (21.7mm vs 19.3mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The TalkBand B3 is the slimmer of the two (12.2mm vs 14.6mm), so it slides under a cuff more easily.
Among the 27 19mm watches we hold thickness for, the TalkBand B1 is thicker than 93% — it will sit high even though the case width reads modest.
We track 40 watches within half a millimetre of the TalkBand B3's 22mm case, across 3 brands.
The TalkBand B3 is 2.4mm wider and 2.4mm thinner than the TalkBand B1.
